| Performance Narrative [Text Block] | The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index and additional indices with investment characteristics similar to those of the Fund for the same period. The Fund uses the Bloomberg U.S. Aggregate Bond Index as its primary benchmark in accordance with regulatory disclosure requirements and uses the ICE BofA U.S. Dollar 3-Month Deposit Offered Rate Constant Maturity Index and the Bloomberg U.S. Universal Bond Index as additional benchmarks that the Investment Adviser believes more closely reflect the Fund’s principal investment strategies. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class A shares. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. Performance for other share classes would differ to the extent they have differences in their fees and expenses.The Fund’s performance prior to May 1, 2016 reflects returns achieved pursuant to different principal investment strategies. If the Fund’s current strategies had been in place for the prior period, the performance information shown would have been different. The Fund's past performance (before and after taxes) is no guarantee of future results.

| Performance Table Narrative | After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans or individual retirement accounts (“IRAs”). In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.After-tax returns are shown for Class A shares only.
